The authors study distributed adaptive beamforming in networks of wireless nodes. In particular, they observe that for the synchronisation of carrier phases, distinct algorithmic configurations are optimal in various environmental settings and propose a protocol that utilises organic computing principles to find optimum parameters. Furthermore, they study the impact of different modulation schemes on the bit error rate of a signal sequence transmitted collaboratively by distributed devices via adaptive beamforming. Beamforming is the approach to combine transmission signals from distinct transmits antennas simultaneously in order to create a superimposed signal with improved channel characteristics at a remote location.
